Delta Verde Laboratory tests for residual solvents using GC-FID/headspace analysis. Extracts and concentrates often contain residues of the solvent used, which may be butane, methanol, acetone, or other liquids.  These residues, even in very small amounts, can give the extracts an unpleasant taste and odor.  The human palate can detect some of these solvents at levels well below one part per million.
